Give content teams a useful control room

Marketing sites live and die by iteration speed. A page builder gives editors speed but fights developers; hand-rolled templates give developers control but bottleneck editors. StreamField sits in the middle.

Sections, not pages

Each section of a landing page is a StructBlock with its own Django template. Editors compose and reorder sections; developers own the templates. Nobody needs a drag-drop page builder.

The result is composition superpowers without the complexity: hero, stats, features, testimonials, pricing, FAQ — each a block, each rendered server-side, each editable in the Wagtail admin.

Why it scales

Blocks are plain Python classes with plain Django templates. New sections ship in a day, and the API serializer and server renderer pick them up automatically from the same field list.

Real StreamField blocks from Loop

A Hero block — the simplest section that starts every page document:

from wagtail import blocks

class HeroBlock(blocks.StructBlock):
    badge = blocks.CharBlock(max_length=80, required=False)
    title = blocks.CharBlock(max_length=200)
    accent = blocks.CharBlock(max_length=60, required=False)
    subtitle = blocks.TextBlock(required=False)
    primary_cta = ButtonBlock(required=False)
    secondary_cta = ButtonBlock(required=False)

    class Meta:
        template = 'content/blocks/hero.html'
        label = 'Hero'

A course page — content-driven with a curriculum StreamField:

class CoursePage(Page):
    title = models.CharField(max_length=255)
    description = RichTextField(blank=True)
    price_cents = models.IntegerField(default=0)
    curriculum = StreamField([
        ('lesson', LessonBlock()),
        ('quiz', QuizBlock()),
    ], use_json_field=True)

    content_panels = Page.content_panels + [
        FieldPanel('description'),
        FieldPanel('price_cents'),
        FieldPanel('curriculum'),
    ]

These blocks ship from one codebase and render on both Django and Astro — the API auto-exposes every field from the same block list.
